// WHEN AI AGENTS USE THIS TOOL

AI agents call listNamespaces to retrieve information from SourceSync Ai MCP Server without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.

// WHY ENFORCE A POLICY ON LISTNAMESPACES

Even though listNamespaces only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.

// RECOMMENDED POLICY

Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

What does the listNamespaces tool do? +

Lists all namespaces available for the current API key and optional tenant ID.. It is categorised as a Read tool in the SourceSync Ai MCP Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on listNamespaces? +

Add a rule in your Intercept YAML policy under the tools section for listNamespaces. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the SourceSync Ai MCP Server MCP server.

What risk level is listNamespaces? +

listNamespaces is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit listNamespaces? +

Yes. Add a rate_limit block to the listNamespaces rule in your Intercept policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block listNamespaces completely? +

Set action: deny in the Intercept policy for listNamespaces. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides listNamespaces? +

listNamespaces is provided by the SourceSync Ai MCP Server MCP server (pbteja1998/sourcesyncai-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
